The "Unofficial" point is based on the official XKCD Geohashing algorithm, but modified for Townsville.
The modifications are that:
This gives a fairly random location within this region.
- the fraction part is divided again by 8 (giving a 0.125°×0.125° graticule), and
- the 'origin' is constantly defined as -19.24°, 146.72°.
The "Double" point uses the original algorithm, but calculates the md5 sum of the md5 sum. The spread of points looks much more random over a short period of time.
